"clarification of the "monopole problem"
[edit]Technically, the "monopole problem" is not that we haven't discovered monopoles yet. The "monopole problem" instead refers to the cosmological implications of grand unification (GUTS). Since monopoles are generically on the menu in GUTS and since they are expected to be quite massive, their existence in the early universe threatens to overclose it. This was considered a "problem" with the standard big bang theory. Cosmic inflation remedies the situation by diluting any primordial abundance of magnetic monopoles (see the wikipedia cosmic inflation page for a discussion of this).- bapowellphysics 18:06, 10 June 2007 (UTC)
Mass / experimental search ???
[edit]Hi, a professor I have for a class said this monopole solution could possibly be discovered by the Large Hadron Collidor. He said the mass is approximently equal to the Mass of the W boson dived by alpha (fine structure constant) ~10TeV. However, I'm not an expert, and I haven't been able to find any sources to back up this claim. I did find out that there is indeed a dedicated monopole detection experiment at the LHC (see the info at MoEDAL_experiment). I think it would be very useful if someone could write a section about experimental searches for this monopole. Regards Danski14(talk) 23:01, 25 November 2011 (UTC)
You mean this? Mind you, this is search for any kind of monopole but as far as I know the detector signature only depends on the charge and the velocity (proton decay cannot be facilitated at these velocities as far as I know) so we have no way to separate Dirac from Polyakov monopoles at the moment. https://en.wikipedia.org/wiki/Magnetic_monopole#Searches_for_magnetic_monopolesP91 (talk) 18:26, 3 March 2020 (UTC)
